How To Use A Keyboard Shortcut To Expand Or Collapse All Folders In Mac Finder

November 30, 2009

While on my Mac, I use the list view in Finder a lot. One thing I had mixed feelings about is the tree-like view that expands folders. It was great, but I wanted a way to quickly collapse or expand folders – and I found out how!

So to quickly expand or collapse folders, all you need to do is to press the left or right arrow keys while a folder is selected. This will expand or collapse it. But I’m guessing that you already knew that – the great thing that I found is, you can first select all folders by pressing ⌘-A, and THEN press the left or right key to expand or collapse every folder.

Neat 😀
